Product Description:

The MT1504A1-E2D1 is a brushless servo motor produced by Kollmorgen as part of the MTC Servo Motors series. It is intended for closed-loop industrial automation where commanded current must translate into accurate rotary motion. Machine controllers can use the motor to index tooling, regulate conveyor velocity, or follow complex profiles without mechanical backlash.

During continuous operation, the drive must supply 2.93 ARMS; at this current, the stator can generate a stall torque of 0.790 N-m with the windings held at 25 °C. Electromagnetic energy storage is characterized by a phase-to-phase inductance of 9.3 mH, a value that influences current-loop bandwidth and the selection of the PWM carrier frequency. The phase resistance is 3.77 Ω, so the electrical time constant is short enough for high-gain control without instability. Windings are insulated for a bus voltage up to 250 VRMS, allowing the motor to connect to compact digital drives that rectify standard factory mains. Mechanical output can reach 6000 rpm, matching the speed class required for lightweight pick-and-place axes and small spindle attachments.

Transient demands are handled by a peak line current of 11 ARMS, allowing the rotor to deliver up to 2.42 N-m during rapid acceleration or impact loading. Under continuous rated conditions, the motor outputs 0.37 kW, and its rotor inertia of 0.0000195 kg·m² keeps servo response crisp while minimizing settling time. Eight magnetic poles interact with a torque constant of 0.258 N-m/ARMS to convert amplifier current into shaft torque with predictable linearity. The assembly weighs only 1.3 kg, so mounting it on end effectors or small gantries adds little mass. At an ambient temperature of 40 °C, the continuous stall capability decreases to 0.742 N-m, which should be considered when the surrounding enclosure lacks forced ventilation.
